Accredited testing, independently vetted.
LabVetted helps homeowners, schools, and facilities choose the right test and an accredited lab, using accreditation records and source links you can check.
Vetted means we check accreditation claims against official sources where available. We do not guarantee provider performance, and we clearly label affiliate or sponsored links. How we verify.
What do you need?
Water, PFAS, lead, mold, radon, or indoor air. Tell us what is going on and we point you to the right test and an accredited lab.
Lead-in-water rules, AHERA asbestos, and PFAS compliance, with requirements, accredited labs, and inspectors by state.
Look up accredited labs through official registries, and the right EPA method for your sample type.
Every lab we list is checked against an official accreditation registry (EPA, NELAP, A2LA, AIHA, or a state program), and each listing links to its verification record. We re-check listings and show when they were reviewed. Sponsored placements are labeled and never change the verification.
